TUF-T-YARN NEEDLE.

To all whom it may concern:

Be it known that we, HORACE VVYMAN, JOHN A. CLARK, and JOHN G.SODERBERG, citizens of the United States, residing at Worcester, in thecounty of Worcester and State of Massachusetts, have ointly inventedcertain new and useful Improvements in Tuft-Yarn Needles, of which thefollowing is a specification.

Our invention relates to tuft yarn needles used in looms for weavingtufted fabrics of the class shown and described in U. S. Letters Patent,No. 446,402.

In looms of the class referred to, the tuft yarn needles extend in avertical direction, and are connected with a jacquard selectingmechanism, and dropped at the desired time to carry the warp yarn intothe warps. In said patent, tubular tuft yarn needles are shown anddescribed, and the object of our invention is to improve upon theconstruction of the tuft yarn needles shown and described in saidpatent.

Our invention consists in certain novel features of construction of ourimprovements as will be hereinafter fully described.

We have only shown in the drawing the portion of a tuft yarn needlewhich embodies our improved construction, sufficient to enable thoseskilled in the art to understand the nature of our improvements.

Referring to the drawing :Figure 1 shows a tuft yarn needle of ourimproved construction with the yarn therein. Fig. 2 shows the oppositeside of the needle shown in Fig. 1. Fig. 3 shows, on an enlarged scale,a detached portion of the tuft yarn needle shown in Fig. 1, without thetuft yarn. Fig. 4 is a longitudinal section, on line 4, 4, Fig. 1,looking in the direction of arrow a, same figure. Fig. 5 shows the reverse side of the needle shown in Fig. 3, looking in the direction ofarrow I), Fig. 4. Fig. 6 corresponds to Fig. 5, but shows the coveredstrip or plate at the lower part removed. Fig. 7 is a longitudinalsection, on line 7, 7, Fig. 6, looking in the direction of arrow 0, samefigure, and, Fig. 8 is a longitudinal section through the cover plateshown in Fig. 5, detached.

In the accompanying drawing, the tuft yarn needle consists of the fiatwire 1, having elongated openings or eyes 2 therein, at certainintervals, through which the tuft yarn 3 is threaded. The tuft yarn 3,shown Specification of Letters Patent.

Serial No. 544,633.

in Figs. 1 and 2, is brought from the creel, not shown, to the upperopening 2, and is threaded back and forth through the openings or eyes 2in the needle, toward the lower end, where the yarn 3 enters through theopening 2 into a tube 1, and emerges at its extreme lower end 1, to bedrawn out to form the tuft on the fabric. The space between two adjacenteyes 2 on the side of the needle along which the yarn 3 alternatelypasses, is preferably made recessed, as shown at 2*, making a groove orrecess through which the tuft yarn 3 passes, and the sides of the grooveact as a guard to protect the tuft yarn from being chafed or rubbed, asthe sets of needles are moved back and forth past each other. loweropening 2 the tuft yarn 3 enters the tubular portion 1, which in thisinstance is made by covering a flat and recessed portion 1, see Fig. 4,with a strip or plate 1", of thin sheet metal, which is preferablysecured at its ends by solder, on the flat wire forming the needle.

The tubular part 1 has enlargements, see Figs. 4, and 7, in which areretaining devices for the yarn 3, which devices in this instance consistof spring blades 4, extending in the direction of the length of thetube, and riveted at their upper ends to the recessed part 1 and also ofspring blades 5 extending in the direction of the length of the tube 1,and riveted at their upper ends to the cover strip 1*. The free ends ofthe spring blades 4 and 5 are preferably made with teeth or serrated, asshown at 4 in Fig. 6. There are in this instance two pair of springblades 4 and 5, although in some instances a single blade may beadvantageously used. The blades act to hold the yarn as it is drawn downthrough the tube 1, and prevent it from being displaced. Theenlargements of the tubular part 1, which contain the spring blades 4and 5, gives a free passage, of the size of the tubular part 1, withinsaid enlargement-s for the yarn 3, as it is drawn through the tube,between the spring blades 4, and 5.

In order to thread the tuft yarn 3 readily, the operator is preferablyprovided with a long wire hooked at one end, which after the yarn hasbeen passed through the openings 2, is attached to the end of the yarnand inserted into the opening 2", and pushed through the tube 1,

At the v between the springs 4 and 5, and out through the lower end 1 ofthe tube, which is made with an open mouth in the direction of itslength for the free passage of the wire and its attached yarn. I

By the construction of the needle as above described, there is acontinuous passage from the upper opening to theextreme lower end of thetube 1, protected by the sides of the groove and the tubular part,whereby the yarn can be freely drawn through the needle 1, and subjectonly to the retaining actions of the springs 4tand 5.

The advantages of our improvements in tuft yarn needles will be readilyappreciated by those skilled in the art.

The pressure of the blades upon the yarn not only causes frictionthereon, but also, by the embedding of the serrated or toothed ends ofthe blades in the yarn, they act to positively hold the yarn from movingback- 1 ward, when the downward movement of the needles, as they arebeing inserted into the warp, turns the spools by the backward pull onthe yarn, and deliver from the spools, yarn for the next row of tufts,all as shown and described in U. S. Letters Patent, No; 466,402, abovereferred to. After the ends 'of the yarn are interwoven into the fabric,an upward movement of the needle, draws a suitable length of yarn forthe next tuft, through the needle, the yarn passing freely between theends of the blades, after which the tuft yarns are cut off in the usualway. The ofiice of the blades 4 and 5 is to permit the yarn to be fed ormoved only in a downward direction, thereby delivering anaccurate lengthof yarn at each operation. 7

It will be understood that the details of construction of ourimprovements may be varied if desired.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent is 1. A tuft yarn needle for looms for weavingtufted fabrics, comprising a flat metal strip having a series ofopenings or eyes therethrough for the tuft yarn, which is threadedthrough said openings on oppositesides, and a tubular portion at itslower end, and retaining or friction devices for the yarn, comprisingspring blades arranged in one or more pairs within the tubular portion,to retain the tuft yarn in a central position within the tube. I 2. Atuft yarn needle for looms for weaving tufted fabrics, comprising a flatmetal strip, having openings or eyes therethrough for the tuft yarn, anda tubular portion at its lower end, and'spring blades within the tubularportion for holding the tuft yarn.

, 3. A tuft yarn needle for looms for weaving tufted fabrics, having aflattened tubular portion at its lower end, with one or more bladestherein, adapted to press upon and engage with the free end of the tuftyarn passing under it, when the yarn is moved backward, and an enlargedspace on said needle for said blades.

4. A tuft yarn needle for looms for weavjing tufted fabrics, having aflattened tubuilar portion at its lower end, with one or jmore pairs ofspring blades therein, adapted .to engage with their free ends a tuftyarn ipassing under them, and retain it from a backward movement, and anenlarged space ion said needle for said blades.

5. A tuft yarn needle for looms for weavf ing tufted fabrics, having aflattened tubular' portion at its lower end, with spring :bladestherein, adapted to retain a tuft yarn passing between them, to preventit from being drawn backward, and having its extreme lower end and openmouth in the direction of the length of the needle.

6. A tuft yarn needle for looms for weavingtufted fabrics, having aflattened tubular portion at its lower end, and an enlarged portion forspring blades, adapted to hold the tuft yarn between them, to prevent itfrom moving, except in one direction.
